This invention aims to provide a novel means for cooking green leafy vegetables and the like, there being no water in the dish in which the vegetables are located, and just enough steam 5 being supplied to cook the vegetables, there being no surplus water to turn away, with a corresponding loss of vitamins.

Another object of the invention is to supply a device of the class described, wherein baking by steam may be accomplished, if the operator wishes.

Another object of the invention is to supply a cooking utensil of the sort alluded to, the capacity of which may be changed by lengthening it vertically and supplying corresponding supple:- mental parts. v V

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains. r

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings:

Fig. 1 shows in vertical section, a device constructed in accordance with the invention;

Fig. 2 is a top plan wherein the cover for the main receptacle has been removed, parts being broken away;

Fig. 3 is a transverse section taken through the device in a plane above the support which is located at the bottom of the main receptacle.

Fig. 4 is a perspective view showing the manipulating hook. V

The device forming the subject matter of this application preferably is made of metal, and comprises a tubular casing, which, as a whole is marked by the numeral I. The casing l embodies a lower member 2 having a bottom 3. The casing I comprises an upper member A, the lower end 5 of which fits within the upper end of the lower member 2, the upper member 4 having an outstanding shoulder 6 which prevents the upper member 6 from sliding downwardly in the lower member 2. In order that the constituent members 2 and i of the casing'l may be handled conveniently, they are supplied with external, oppositely disposed handles 1. The upper member t of the casing l is surmounted by a removable cover 8 having a handle 9. A water receiver 10 is secured to the outer surface of the lower member 22, at the lower end of said member. A lid H has its outer edge hinged at l2 to the receiver H], the inner edge of the lid fitting closely about the lower member 2, to prevent the loss of steam. In the lower member 2 there is an opening M which communicates with the water receiver It).

In the lower end of the casing I is placed an inverted cup-shaped support !5, including an annular body l5, spaced slightly from the lower member 2, the body iii of the support resting on the bottom 3 of the lower member 2. The support !5 includes a funnel-shaped top H, carrying a central upstanding flue I8, supplied with perforations 89. The top ll has upstanding U-shaped handles 2E, There are openings ill in the top I? and the body iii of the support i5 is provided with openings 22, one of 'which may be registration with the opening l4 that leads to the water receiver ID, although water from the receiver will findits way into the support l 5 below the top H, through any of the openings 22 in the body 56 since the body 16 is spaced from the lower member 2 of the casing l, as mentioned hereinbeforc and as shown in Fig. l.

The numeral 23 marks a cooking dish located in the lower member 2 of the casing l and having flat bottom resting at its periphery on the top ll of the support t5, the bottom of the dish 23 resting also, on the handles 20 of the support 15. The cooking dish 23 has outstanding handles 24 which, cooperating with the member 2 of the casing l, centralize the cooking dish 23 in the lower member 2.

The bottom of the cooking dish 23 is equipped with an upstanding sleeve 25, surrounding, but spaced from the flue l8 that is carried by the top I l of the support I '5. The sleeve 25 terminates in spaced relation to an inverted funnel shaped cover 25 mounted removably on the dish 23 and provided with upstanding loop-shaped handles 56. At its apex, the cover 26 has a central opening 27, through which the flue l8 passes, there being, however, no steam-tight joint at the opening 21.

The numeral 28 designates a baking dish, constructed like the cooking dish 23 and supported on the handles 56 of the cover 25 of the cooking dish 23. The baking dish 28 has outstanding handles 29, functioning like the handles 24. The sleeve of the baking dish 28 is marked by the numeral 36. The dish 28 carries a removable cover 3! having handles 32. The essential difference between the dish 26 and the dish 23 is that the cover 3! of the dish 28 has a central depending tubular neck 33 which fits closely within the sleeve 33 of the dish 28.

The lower end of a removable flue extension 35 fits frictionally in the upper end of the main part 18 of the flue, so that the flue extension 3 will not'slide down freely from the position shown in Fig. 1. The flue extension 34 projects upwardly into the upper member A of the casing l and has perforations 35.

Within the casing! is disposed a baking dish 36, having a flat bottom 31 supplied with openings or seats 33. The bottom 31 of the baking dish 36, carries a fixed tubular sieeve 35 which extends upwardly and downwardiy with respect to the bottom. 3'! of the baking dish. The lower end of the sleeve 39 rests on the cover 3! of the dish 28 and carries an outstanding disk like platform 46. Cups or containers ill and 52 are mounted removably in the seats 38 of the bottom 37 of the dish 36. If some of the cups, such as the cup 42 of Fig. 1, are long enough, they will be supported on the platform 49. This dish 36 has outstanding handles 43 corresponding to the handles 29 and 24. On the dish 35 is mounted an inverted funnel shaped cover M having handles 45. The cover id has a depending neck 46, making a tight within the upper end of the sleeve 39 or" the dish 36, the neck 2'6, however, being spaced from the flue extension 3 3.

When the parts are arranged as shown .in Fig. 1, a small quantity of water may be poured into the receiver I' 0, the water finding its way through the openings l4 and 22, into the support l5, below the top ll of the support. If heat is applied 'to the casing i, steam is created in the lower end of the casing, and the steam rises in the casing 5, around the outside of the dishes 23, 28 and 36. Steam rises also through the flue l8 and its extension 36. As the steam rises in the flue i8, some of the steam passes through the perforations it, and some of the steam passes through the sleeve 25, into the dish 23, just enough moisture being added to the material in the dish 23 to effect a proper steaming or cooking, without creating surplus water to be drained away with a corresponding loss of vitamins.

The steam passes upwardly through the flue 18, but does not enter the dish 28, because the neck 33 on the cover iii of the dish 23 fits tightly within the sleeve 30 on the bottom of said dish. The material in the dish 28, therefore, may be baked by steam, but is not subjected directly to the action of the steam. 'As the steam moves upwardly through the extension 34 of the flue, the steam does not enter the dish 36, because the neck 36 on the cover 4 1 of the dish fits tightly the upper end of the sleeve 39 which is carried by the bottom of the said dish. The material in the cups 42 and ii, therefore, or in the dish 36, about the cups, is steam oaked but is not subjected to the direct action of the steam.

If the operator wishes, he mayremove the upper member 4 of the casing, the dish 35 and associated parts, and the flue extension 34, the cover 8 then being placed directly upon the upper end of the lower member 2 of the casing l.

In practice, two of the covers, 3! and two of the covers 26 are supplied. Therefore, the cover SI of Fig. 1 may be replaced by a cover constructed like the cover 2'6. Then the material in both of the dishes 23 and 28 will be steamed. It is possible, likewise, to replace the cover of Fig. 1 by a cover constructed like the cover 3 l, and then the contents of both dishes 28 and 23 will be baked, rather than steamed or cooked.

For convenience in handling any movable parts of the device, there is supplied the hook 4'! of Fig. 4, said hook carrying a laterally offset grip t3.
